Python: Fix OpenAIChatCompletionClient passing raw JSON-Schema dict response_format through unwrapped

[Binit Mohanty (exp-ouroborous)]

Motivation and Context

Raw JSON-Schema dicts (e.g. {"type": "object", "properties": {...}}) passed as response_format are forwarded to the Chat Completions API verbatim, and OpenAI rejects them with a 400 (Invalid value: 'object'). The Responses-based OpenAIChatClient already auto-wraps the identical input (see _convert_response_format), so the two clients disagree on the same input. This bites the declarative path in particular, where the loader passes outputSchema.to_json_schema() output as a bare dict.

Description

• Fixes Python: [Bug]: OpenAIChatCompletionClient passes raw JSON-Schema dict response_format through unwrapped (OpenAIChatClient/Responses auto-wraps the same input) #7197
• Adds _normalize_response_format_dict: mirrors the Responses client's raw-schema detection (JSON-Schema primitive types / schema keywords), wraps into the {"type": "json_schema", "json_schema": {...}} envelope with additionalProperties: false injection and title → name promotion.
• Dicts already using a valid response_format type (json_schema / json_object / text) pass through unchanged — the existing test_response_format_dict_passthrough still passes.
• New tests: raw-schema wrapping, title→name promotion, json_object passthrough.

Contribution Checklist

• The code builds clean without any errors or warnings
• The PR follows the Contribution Guidelines
• All unit tests pass, and I have added new tests where possible (test_openai_chat_completion_client.py: 77 passed, 20 skipped)
• Is this a breaking change? No — previously-rejected inputs now work; valid inputs are unchanged.

Pull request overview

This PR fixes Python OpenAIChatCompletionClient handling of response_format when callers pass a raw JSON-Schema dict by normalizing/wrapping it into the Chat Completions json_schema envelope (bringing it in line with the Responses-based client), and adds unit tests for the new behavior. It also introduces a new .NET “AgentLearn” learning project plus several large research/ markdown documents and repo-level developer settings.

Changes:

• Python: normalize raw JSON-Schema dict response_format values in OpenAIChatCompletionClient and add tests for wrapping/title→name behavior.
• .NET: add dotnet/learn/AgentLearn sample app (workflows + HITL + tests) and a dotnet/samples/run.bash helper script.
• Docs/config: add research/ documentation, new dotnet/learn docs/config, and repo-level VS Code/default-solution and gitignore updates.

Note for reviewers: the earlier review threads (research/, dotnet/learn/, .vscode/settings.json, AgentLearn.csproj) referenced unrelated files accidentally included from a stale fork base — the branch has been rebuilt as a single commit on top of main and those files are no longer part of this PR (now 2 files: _chat_completion_client.py + its tests).
